I want to make my alarm clock “smart”. I'm very new to this stuff, that is, the hardware side. The programming shouldn't present too many problems.
I’m currently experimenting with a simulator (http://circuits.io) and want to start with controlling the alarm’s buzzer with my Arduino.
I did some reading on transistors and this is what I came up with:
I’ve turned pin D3 to high and hooked it up to the base of a NPN transistor. I’m trying to run 1.5V through the transistor, but nothing happens. Any thoughts?
